Pages raises KeyError when requesting 'HTTP_HOST' for use in custom apps

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use middleware dependant on 'HTTP_HOST'
2. For example: http://www.djangosnippets.org/snippets/1119/
3. Access admin pages - Key error 'HTTP_HOST' raised

What is the expected output? What do you see instead?
Error raised by: 

domain = request.META['HTTP_HOST']

In below code, as middleware, called in settings.py middleware as custom.

Effectively doesn't recieve 'HTTP_HOST' from the server. Seems to be
triggered in particular by cache pages_tags. Don't have the experience to
be able to debug beyond this point.

What version of the product are you using? On what operating system?
Latest trunk, on Apache2, Python 2.5

Please provide any additional information below.

Here's the middleware code:
    def process_request(self, request):
        domain_parts = request.get_host().split('.')
        if (len(domain_parts) > 2):
            subdomain = domain_parts[0]
            if (subdomain.lower() == 'www'):
                subdomain = ''
            domain = '.'.join(domain_parts[1:])
        else:
            subdomain = ''
            domain = request.META['HTTP_HOST']

        request.subdomain = subdomain
        request.domain = domain

That's fixed it batiste, yes it's the undefined HTTP HOST that's the issue. I 
can see
it was reported int he snippet also, but ther updated code wasn't applied 
correctly.

Thanks for picking that up.
